<pre>In ngx_pagespeed <a href="https://github.com/pagespeed/ngx_pagespeed">https://github.com/pagespeed/ngx_pagespeed</a> build instructions,
a static .a library which has an __init_array (prebuilt with gcc and provideed)
in it doesn't link properly.
If nginx is built with gcc, the __init_array gets populated
if nginx is built with clang, the __init_array is empty.
for an example see <a href="https://gist.github.com/crowell/9952fa514e8b861e5d66">https://gist.github.com/crowell/9952fa514e8b861e5d66</a>
I've tried using clang 3.4 which came with epel, and the gcc toolchain from
devtoolset, as well as the gcc toolchain from a source built gcc 5.1, and a
source built clang 3.7 with both gcc toolchains.
the gcc compiled code always has the __init_array populated, and the clang
compiled code never does.
to reproduce follow these instructions on centos 6.7
<a href="https://developers.google.com/speed/pagespeed/module/build_ngx_pagespeed_from_source">https://developers.google.com/speed/pagespeed/module/build_ngx_pagespeed_from_source</a>
but export CC="clang --gcc-toolchain=/opt/rh/devtoolset-2/root/usr/" or
whatever path points to a c++11 compatible gcc toolchain.</pre>
